So this week, things have been pretty slow for me and my girlfriend. I've been kinda busy lately and havn't been seeing her much around school (we're in 3rd year of Dentistry school and we've been together for 5 months). We get a long very well and hardly get in arguments- We're honestly a pretty good couple i'd say , much better than the majority out there.

Anyways, this week idk why, i've felt a little tired of her (IDK WHY - i dont want to - i love her), last weekend I went partying without her (invited her but she couldnt go, she stayed home). I told her everyone was gonna get really drunk and there were going to be weed brownies and everything beforehand but she couldnt go. Anyways i did get pretty drunk but i'm not the cheating type but I did talk to a couple girls. She woke up the next morning sad and depressed texting me she had a dream that I was cheating on her - she was emotional the whole day and wanted to see me and everything.
Now this week i havn't seen her much at school but when I do it's only like 5 minutes a day cause i've been busy with patients and stuff, last night while we were texting, during our normal convo she said "i will never get bored with you babe, you make me so happy and you're always making me laugh!"
IDK if this shit has a double-meaning, or if she senses that i'm getting a little detached maybe ... or maybe i'm possibly over-thinking! She's a very good person and I do want to make it last but i need tips! Do you get naturally detached if you don't see her that much lately? maybe that's the prob

Just this week? It's only been three days into the week.

Relax, stop thinking so much into it. Sometimes you just have slow or busy weeks and don't get to see one another very much. It happens. If you're so worried just ask her out to the cinema or something. She's not gonna turn you down.
